“…This is the goal of the "W-band Analysis and VErification" (WAVE) program (2004-on going) of the Italian Space Agency (ASI), that aims at the exploitation of the W-band (75-110 GHz range) for broadband satellite communications [11,12]. The program is undertaken by a large team of aerospace industries and scientific institutions.…”

Integration and convergence of different access technology is a key concept of 4G systems. This integration also includes the interface among terrestrial and aero-space components, whose importance has been so far under-estimated and not deeply understood. In this paper, a layered model of the 4G integrated network vision is introduced, highlighting details about the aero-space component. The concept of integration is discussed under different viewpoints, particularly highlighing integration among aero-space segments and related services (i.e. navigation). Examples of integration scenarios identified and investigated in the frame of research programs co-funded by Italian institutions are also displayed in the paper.

“…For GMSK, unmodulated data (rectangular-shaped pulses) are processed by a LPF filter, having Gaussian-shaped frequency response, before frequency modulation [10]. This filter greatly reduces the spectral sidelobes with 6 respect to MSK signals [10] [15]. The introduction of the Gaussian filter involves a decrease of efficiency due to the increase of ISI.…”

In the EHF (Extremely High Frequency) domain, W-band (75-110 GHz) offers promising perspectives for future satellite communications, mainly in terms of large bandwidth availability for high-bit-rate transmission. In this work 1 , an innovative physical (PHY) layer design for broadband satellite connections operating in W-band is proposed, which is based on the Prolate Spheroidal Wave Functions (PSWFs). PSWF waveforms (originally proposed in short-range indoor Ultra Wideband (UWB) communications) are aimed at optimizing the tradeoff between the concentration of pulse energy in a finite time interval and in a limited bandwidth. In our paper, PSWF-based 4-ary PSM modulation, characterized by a nearoptimal compromise between spectral and envelope compactness, has been tested for the radio interface of a W-band geostationary (GEO) downlink connection. The effect of nonlinear distortions, introduced by power-efficient saturating amplifiers, can be drastically reduced without any power back-off and maintaining a very good spectral efficiency. Experimental results, obtained by means of realistic simulations, fully demonstrate the potential advantages taken by PSWF in terms of increased spectral efficiency, link availability and net payload rate with respect to state-of-the-art pulse-shaped modulations (raised-cosine filtered QAM and Gaussian Minimum Shift Keying), commonly employed in satellite communications.

“…In such a framework, a recent scientific experiment carried on by the Italian Space Agency (ASI), namely the DAVID-DCE experiment [3], was aimed at exploring the technical feasibility of the exploitation of the W-band (70-110GHz) [2] for wideband LEO satellite transmission in scientific missions. A step-ahead with respect to the DAVID experiment is represented by the WAVE (W-band Analysis and Verification) project [4]. WAVE is a feasibility study funded by ASI in 2004 aimed at providing some guidelines for the actual deployment of commercial services exploiting W-band satellite connections.…”

Abstract-Recent efforts in satellite communication research considered the exploitation of higher frequency bands as a valuable alternative to conventional spectrum portions. An example of this can be provided by the Wband (70-110GHz). Recently, a scientific experiment carried on by the Italian Space Agency (ASI), namely the DAVID-DCE experiment, was aimed at exploring the technical feasibility of the exploitation of the W-band for broadband networking applications. Some preliminary results of DAVID research activities pointed out that phase noise and high Doppler-shift can severely compromise the efficiency of the modulation system, particularly for what concerns the aspects related to the carrier recovery. This problem becomes very critical when the use of spectrally efficient M-ary modulations is considered in order to profitably exploit the large amount of bandwidth available in the W-band. In this work 12 , a novel carrier recovery algorithm has been proposed for a 16-QAM modulation and tested, considering the presence of phase noise and other kinds of non-ideal behaviors of the communication devices typical of W-band satellite transmission. Simulation results demonstrated the effectiveness the proposed solution for carrier recovery and pointed out the achievable spectral efficiency of the transmission system, considering some constraints about transmitted power, data BER and receiver bandwidth.
